Switch it to a months prep and you'll get the same result. Iron Man has all of SHIELD working for him now. He could create synthetic kryptonite, spray the crap on his sturdiest armor, and just wait Supes out. Thats assuming he doesnt take the time to form the stuff into some type of energy weapon. If dumbass Metallo can give Supes trouble, Tony can mop the floor with him while drinking a martini.

We have Stark, who is already a master of weapons tech and powered armor and now he knows Superman's weaknesses to kryptonite and magic. He'd build a suit like Luthor's with the kryptonite and pull in some mystical gadgets from some of his magical allies. He'd probably figure out a way to project some simulated red sun radiation while projecting a force field that blocked the normal yellow sun radiation.
Superman's raw power might still make it a fight but, without PIS, Stark would win.
